     represent the shares of Frontier Common Stock into which such ALC Common

     Stock has been converted.  Certificates previously representing shares of

     ALC Common Stock shall be exchanged for certificates representing whole

     shares of Frontier Common Stock issued in consideration therefor upon the

     surrender of such certificates in accordance with Section 2.2, without

     interest.

referred to as the "Exchange Fund") issuable pursuant to Section 2.1 in exchange

for outstanding shares of ALC Common Stock.

          (b)  Exchange Procedures.  As soon as reasonably practicable after the

Effective Time, Frontier shall instruct the Exchange Agent to mail to each

holder of record of a certificate or certificates which immediately prior to the

Effective Time represented outstanding shares of ALC Common Stock (the

"Certificates"), (i) a letter of transmittal (which shall specify that delivery

shall be effected, and risk of loss and title to the Certificates shall pass,

only upon proper delivery of the Certificates to the Exchange Agent and shall be

in such form and have such other provisions as Frontier and ALC may reasonably

specify) and (ii) instructions to effect the surrender of the Certificates in

exchange for certificates representing shares of Frontier Common Stock.  Upon

surrender of one or more Certificates for cancellation to the Exchange Agent

together with such letter of transmittal, duly executed, and such other

customary or other reasonable documents as may be required pursuant to such

instructions, the holder of such Certificates shall be entitled to receive in

exchange therefor a certificate representing that number of whole shares of

Frontier Common Stock which such holder has the right to receive in respect of

the Certificates surrendered pursuant to the provisions of this Article II, and

the Certificates so surrendered shall forthwith be cancelled.  In the event of a

transfer of ownership of ALC Common Stock which is not registered in the

transfer records of ALC, a certificate representing the proper number of shares

of Frontier Common Stock may be issued to a transferee if the Certificate

representing such ALC Common Stock is presented to the Exchange Agent,

accompanied by all documents required to evidence and effect such transfer and

by evidence that any

                                                                          6

applicable stock transfer taxes have been paid.  Until surrendered as

contemplated by this Section 2.2, each Certificate shall be deemed at any time

after the Effective Time to represent only the right to receive upon such

surrender a certificate representing shares of Frontier Common Stock and cash in

lieu of any fractional shares of Frontier Common Stock as contemplated by this

Section 2.2.

          (c)  Distributions with Respect to Unexchanged Shares.  No dividends

or other distributions declared or made after the Effective Time with respect to

Frontier Common Stock with a record date after the Effective Time shall be paid

to the holder of any unsurrendered Certificate with respect to the shares of

Frontier Common Stock represented thereby, and no cash payment in lieu of

fractional shares shall be paid to any such holder pursuant to Section 2.2(e)

until the holder of such Certificate shall surrender such Certificate.  Subject

to the effect of applicable laws, following surrender of any such Certificate,

there shall be paid to the holder of the certificates representing whole shares

of Frontier Common Stock issued in exchange therefor, without interest, (i) at

the time of such surrender or as promptly thereafter as practicable, the amount

of any cash payable with respect to a fractional share of Frontier Common Stock

to which such holder is entitled pursuant to Section 2.2(e) and the amount of

dividends or other distributions with a record date after the Effective Time

theretofore paid with respect to such whole shares of Frontier Common Stock, and

(ii) at the appropriate payment date, the amount of dividends or other

distributions with a record date after the Effective Time but prior to surrender

and a payment date subsequent to surrender payable with respect to such whole

shares of Frontier Common Stock.

          (d)  No Further Ownership Rights in ALC Common Stock.  All shares of

Frontier Common Stock issued upon conversion of shares of ALC Common Stock in

accordance with the terms hereof (including any cash paid pursuant to Section

2.2(c) or 













<PAGE>
                                                                          7

2.2(e)) shall be deemed to have been issued in full satisfaction of all rights

pertaining to such shares of ALC Common Stock, and there shall be no further

registration of transfers on the stock transfer books of the Surviving

Corporation of the shares of ALC Common Stock which were outstanding immediately

prior to the Effective Time.  If, after the Effective Time, Certificates are

presented to the Surviving Corporation for any reason, they shall be cancelled

and exchanged as provided in this Article II.

          (e)  No Fractional Shares.  No certificates or scrip representing

fractional shares of Frontier Common Stock shall be issued upon the surrender

for exchange of Certificates, and such fractional share interests will not

entitle the owner thereof to vote or to any rights of a stockholder of Frontier.

In lieu of any such fractional shares, each holder of ALC Common Stock upon

surrender of a Certificate for exchange pursuant to this Section shall be paid

an amount in cash (without interest), rounded to the nearest cent, equal to the

product obtained by multiplying the fractional share interest to which such

holder would otherwise be entitled (after taking into account all shares of ALC

Common Stock then held by such holder) by the closing price for a share of

Frontier Common Stock on the NYSE Composite Transaction Tape on the first

business day immediately preceding the Effective Time.  For this purpose, shares

of any holder represented by two or more certificates may be aggregated, and in

no event shall any holder be paid any amount in respect of more than one share

of Frontier Common Stock.

          (f)  Termination of Exchange Fund.  Any portion of the Exchange Fund

which remains undistributed to the stockholders of ALC for six months after the

Effective Time shall be delivered to Frontier upon demand, and any stockholders

of ALC who have not theretofore complied with this Article II shall thereafter

look only to Frontier for payment of

                                                                          8

their claim for Frontier Common Stock, any cash in lieu of fractional shares of

Frontier Common Stock and any dividends or distributions with respect to

Frontier Common Stock.

          (g)  No Liability.  Neither Frontier nor ALC shall be liable to any

holder of shares of ALC Common Stock or Frontier Common Stock, as the case may

be, for such shares (or dividends or distributions with respect thereto) or cash

from the Exchange Fund delivered to a public official pursuant to any applicable

abandoned property, escheat or similar law.

          (h)  Withholding Rights.  Frontier or the Exchange Agent shall be

entitled to deduct and withhold from the consideration otherwise payable

pursuant to this Agreement to any holder of shares of ALC Common Stock such

amounts as Frontier or the Exchange Agent is required to deduct and withhold

with respect to the making of such payment under the Code, or any provision of

state, local or foreign tax law, or any court order.  To the extent that amounts

are so withheld by Frontier or the Exchange Agent, such withheld amounts shall

be treated for all purposes of this Agreement as having been paid to the holder

of the shares of ALC Common Stock in respect of which such deduction and

withholding was made by Frontier or the Exchange Agent.

                                                                          9

incorporation or organization, has all requisite power and authority and all

necessary governmental approvals to own, lease and operate its properties and to

carry on its business as it is now being conducted and is duly qualified and in

good standing to do business in each jurisdiction in which the nature of its

business or the ownership or leasing of its properties makes such qualification

necessary other than in such jurisdictions where the failure to be so organized,

existing or in good standing or to have such power, authority and governmental

approvals or so to qualify would not, individually or in the aggregate, have a

material adverse effect on ALC.  As used in this Agreement, (i) a "Significant

Subsidiary" means any subsidiary of ALC or Frontier, as the case may be, that

Rule 1-02 of Regulation S-X of the Securities and Exchange Commission (the

"SEC"), (ii) any reference to any event, change or effect being "material" with

respect to any entity means an event, change or effect which is material in

relation to the condition (financial or otherwise), prospects, properties,

assets, liabilities, businesses or operations of such entity and its

subsidiaries taken as a whole and (iii) the term "material adverse effect"

means, with respect to ALC or Frontier, a material adverse effect on the

business, assets, prospects, results of operations or financial condition of

such party and its subsidiaries taken as a whole or on the ability of such party

(and, with respect to Frontier, of Sub) to perform its obligations hereunder.

          (b)  Capital Structure.  (i)  As of the date hereof, the authorized

capital stock of ALC consists of 200,000,000 shares of ALC Common Stock and

15,500,000 shares of Preferred Stock, par value of $.01 per share, of which

500,000 shares have been designated as Series E Participating Preferred Stock

       (iii)  No consent, approval, order or authorization of, or registration,

and (2) such other filings under the Securities Exchange Act of 1934, as amended

<PAGE>
                                                                         15

Improvements Act of 1976, as amended (the "HSR Act"), and (E) filings under the

Communications Act of 1934, as amended (the "Communications Act"), and under

state or foreign utility or telecommunication regulatory laws.

          (d)  SEC Documents.  ALC has made available to Frontier a true and

complete copy of each report, schedule, registration statement and definitive

proxy statement filed by ALC with the SEC since January 1, 1992 (as such

documents have since the time of their filing been amended, the "ALC SEC

Documents"), which are all the documents (other than preliminary material) that

ALC was required to file with the SEC since such date.  As of their respective

dates, the ALC SEC Documents complied in all material respects with the

requirements of the Securities Act of 1933, as amended (the "Securities Act"),

or the Exchange Act, as the case may be, and the rules and regulations of the

SEC thereunder applicable to such ALC SEC Documents, and none of the ALC SEC

Documents contained any untrue statement of a material fact or omitted to state

a material fact required to be stated therein or necessary to make the

statements therein, in light of the circumstances under which they were made,

not misleading.  The financial statements of ALC included in the ALC SEC

Documents comply as to form in all material respects with applicable accounting

requirements and with the published rules and regulations of the SEC with

respect thereto, have been prepared in accordance with generally accepted

accounting principles applied on a consistent basis during the periods involved

(except as may be indicated in the notes thereto or, in the case of the

unaudited statements, as permitted by Form 10-Q of the SEC) and fairly present

the consolidated financial position of ALC and its consolidated subsidiaries as

at the dates thereof and the consolidated results of their operations and cash

flows for the periods then ended.  All material agreements, contracts and other

documents required to be filed as exhibits to any of the ALC SEC Documents have

been so filed.

                                                                         16

          (e)  Information Supplied.  None of the information supplied or to be

supplied by ALC for inclusion or incorporation by reference in (i) the

registration statement on Form S-4 to be filed with the SEC by Frontier in

connection with the issuance of shares of Frontier Common Stock in the Merger

(the "S-4") will, at the time the S-4 is filed with the SEC and at the time it

becomes effective under the Securities Act, contain any untrue statement of a

material fact or omit to state any material fact required to be stated therein

or necessary to make the statements therein, in light of the circumstances under

which they were made, not misleading, and (ii) the Proxy Statement will, at the

date of mailing to stockholders and at the times of the meetings of stockholders

to be held in connection with the Merger, contain any untrue statement of a

material fact or omit to state any material fact required to be stated therein

or necessary in order to make the statements therein, in light of the

circumstances under which they were made, not misleading.  The Proxy Statement

(except for such portions thereof that relate only to Frontier) will comply as

to form in all material respects with the provisions of the Exchange Act and the

rules and regulations thereunder.

          (f)  Compliance with Applicable Laws.  ALC and its subsidiaries hold

all permits, licenses, variances, exemptions, orders and approvals of all

Governmental Entities which are material to the operation of the businesses of

ALC and its subsidiaries, taken as a whole (the "ALC Permits"), except to the

extent the failure to hold the ALC Permits will not have a material adverse

effect on ALC.  ALC and its subsidiaries are in compliance with the terms of the

ALC Permits and all applicable laws and regulations, except where the failure so

to comply would not have a material adverse effect on ALC.  Except as disclosed

in the ALC SEC Documents filed prior to the date of this Agreement, the

businesses of ALC and its subsidiaries are not being conducted in violation of

any law, order, ordinance or regulation of any Governmental Entity, except for

possible violations which individually or in the aggregate 













<PAGE>
                                                                         17

do not, and, insofar as reasonably can be foreseen, in the future will not, have

a material adverse effect on ALC.  As of the date of this Agreement, to the

knowledge of ALC, no investigation by any Governmental Entity with respect to

ALC or any of its subsidiaries is pending or threatened, other than, in each

case, those the outcome of which, as far as reasonably can be foreseen, will not

have a material adverse effect on ALC.

          (g)  Litigation.  As of the date of this Agreement, except as

disclosed in the ALC SEC Documents filed prior to the date of this Agreement,

there is no suit, action or proceeding pending or, to the knowledge of ALC,

threatened, against or affecting ALC or any subsidiary of ALC as to which there

is a reasonable possibility of an adverse determination and which, if adversely

determined, would, individually or in the aggregate, have a material adverse

effect on ALC, nor is there any judgment, decree, injunction, rule or order of

any Governmental Entity or arbitrator outstanding against ALC or any subsidiary

of ALC or which, insofar as reasonably can be foreseen, in the future could

have, any such effect.

          (h)  Taxes.  ALC and each of its subsidiaries (and any consolidated,

combined, unitary or aggregate group for tax purposes of which ALC or any of its

subsidiaries is or has been a member) have timely filed all tax returns required

to be filed by any of them and have paid (or ALC has paid on their behalf), or

have set up an adequate reserve for the payment of, all taxes required to be

paid as shown on such returns, and the most recent financial statements

contained in the ALC SEC Documents reflect an adequate reserve for all taxes

payable by ALC and its subsidiaries (whether or not shown on such returns)

accrued through the date of such financial statements.  Except as set forth on

Schedule 3.1(h), no material deficiencies for any taxes have been proposed,

asserted or assessed against ALC or any of its subsidiaries that are not

adequately reserved for, no audit of any tax return of ALC or any of its

subsidiaries is being conducted by a tax authority, and no extension of the

statute of

                                                                         18

limitations on the assessment of any taxes has been granted to ALC or any of its

subsidiaries and is currently in effect.  For the purpose of this Agreement, the

term "tax" (including, with correlative meaning, the terms "taxes" and

"taxable") shall include, except where the context otherwise requires, all

federal, state, local and foreign income, profits, franchise, gross receipts,

payroll, sales, employment, use, property, withholding, excise, occupancy and

other taxes, duties or assessments (including assessments against

telecommunications providers for universal service support, disabled access,

emergency communications (911) and other purposes mandated by law, regulation or

order of any Governmental Entity) of any nature whatsoever, together with all

interest, penalties and additions imposed with respect to such amounts, and the

term "tax return" shall mean any return, report or statement required to be

filed with any governmental authority with respect to taxes.

          (i)  Certain Agreements.  Except as disclosed in the ALC SEC Documents

filed prior to the date of this Agreement, except as set forth on Schedule

3.1(i) hereto and except for this Agreement, as of the date of this Agreement,

neither ALC nor any of its subsidiaries is a party to any oral or written (i)

consulting agreement involving the payment of more than $250,000 per annum, or

union, guild or collective bargaining agreement which agreement covers any

employees, (ii) agreement with any executive officer or other key employee of

ALC or any subsidiary of ALC the benefits of which are contingent, or the terms

of which are materially altered, upon the occurrence of a transaction involving

ALC or any subsidiary of ALC of the nature contemplated by this Agreement and

which provides for the payment of in excess of $250,000, (iii) agreement with

respect to any executive officer of A or any subsidiary of ALC providing any

plan,

restricted stock plan or stock purchase plan, any of the benefits of which will

          (m)  Section 203 of the DGCL Not Applicable.  The restrictions of

Section 203 of the DGCL will not, prior to the termination of this Agreement,

assuming the accuracy of the representations contained in Section 3.2(r)

Agreement, the Merger or the transactions contemplated hereby.

          (n)  Vote Required.  The affirmative vote of the holders of a majority

          (p)  ALC Rights Agreement.  Concurrently with the execution and

delivery of this Agreement, ALC has amended the ALC Rights Agreement, to provide

that (i) none of the approval, execution or delivery of this Agreement or the

consummation of the Merger will cause (1) the ALC Rights to become exercisable

under the ALC Rights Agreement, (2) Frontier or any of its subsidiaries to be

deemed an "Acquiring Person" (as defined in the ALC Rights Agreement), or (3)

the "Stock Acquisition Date" (as defined in the ALC Rights Agreement) to occur

upon any such event and (ii) the "Expiration Date" (as defined in the ALC Rights

Agreement) of the ALC Rights shall occur immediately prior to the Effective

Time.  The "Distribution Date" (as defined in the ALC Rights Agreement) has not

occurred.

          (q)  Properties.  Except as disclosed in the ALC SEC Documents filed

prior to the date of this Agreement, ALC or one of its subsidiaries (i) has

good, clear and marketable title to all the properties and assets reflected in

the latest audited balance sheet included in such ALC SEC Documents as being

owned by ALC or one of its subsidiaries or acquired after the date thereof which

are material to ALC's business on a consolidated basis (except properties sold

or otherwise disposed of since the date thereof in the ordinary course of

business), free and clear of all claims, liens, charges, security interests or

encumbrances of any nature whatsoever except (A) statutory liens securing

payments not yet due and (B) such imperfections or irregularities of title,

claims, liens, charges, security interests or encumbrances as do not materially

affect the use of the properties or assets subject thereto or affected thereby

or otherwise materially impair business operations at such properties and (ii)

is the lessee of all leasehold estates reflected in the latest audited financial

statements included in such ALC SEC Documents or acquired after the date thereof

which are material to its business on a consolidated basis (except for leases

the properties purported to be leased thereunder, and each such lease is valid

without default thereunder by the lessee or, to ALC's knowledge, the lessor.

neither ALC nor, to its best knowledge, any of its affiliates or associates (as

defined under the Exchange Act), (i) beneficially own, directly or indirectly,

or (ii) are parties to any agreement, arrangement or understanding for the

purpose of acquiring, holding, voting or disposing of, any shares of Frontier

Common Stock, except for shares which may be held by ALC Benefit Plans which

          (s)  Intellectual Property.  ALC and its Significant Subsidiaries own

or possess adequate licenses or other valid rights to use all material computer

software and firmware, patents, patent rights, trademarks, trademark rights,

secrets, applications for trademarks and for service marks, know-how and other

proprietary rights and information used or held for use in connection with the

business of ALC and its Significant Subsidiaries as currently conducted or as

contemplated to be conducted, and ALC is unaware of any assertion or claim

challenging the validity of any of the foregoing which, individually or in the

aggregate, would have a material adverse effect.  To the best knowledge of ALC,

except as disclosed on Schedule 3.1(s) hereto, the conduct of the business of

ALC and its Significant Subsidiaries as currently conducted does not conflict in

any way with any patent, patent right, license, trademark, trademark right,

trade name, trade name right, service mark or copyright of any third party that,

individually or in the aggregate, would have a material adverse effect.  To the

best knowledge of ALC, there are no infringements of any proprietary rights

owned by or licensed by or to ALC or any of its Significant Subsidiaries which,

individually or in the aggregate, would have a material adverse effect.

          (t)  Undisclosed Liabilities.  Except as disclosed in the ALC SEC

Documents filed prior to the date of this Agreement, neither ALC nor any of its

Significant Subsidiaries has incurred any liabilities or obligations (absolute,

accrued, contingent or otherwise) other than liabilities or obligations which

would not, individually or in the aggregate, have a material adverse effect.

          (u)  Environmental Matters.  (i) Except as disclosed in the ALC SEC

Documents filed prior to the date of this Agreement, there are no Environmental

Liabilities

(as defined below) of ALC or any of its Significant Subsidiaries which would,

individually or in the aggregate, have a material adverse effect.

          (ii) As used in this Agreement, "Environmental Laws" means any and all

federal, state, local or municipal laws, rules, orders, regulations, statutes,

ordinances, codes, decisions, injunctions, orders, decrees, requirements of any

Governmental Entity, any and all common law requirements, rules and bases of

liability regulating, relating to or imposing liability or standards of conduct

concerning pollution, Hazardous Materials or protection of human health or the

environment, as now or may at any time hereafter be in effect.  "Environmental

Liabilities" with respect to any person means any and all liabilities of or

relating to such person or any of its Significant Subsidiaries (including any

entity which is, in whole or in part, a predecessor of such person or any of

such Subsidiaries), whether vested or unvested, contingent or fixed, actual or

potential, known or unknown, which (i) arise under or relate to matters covered

by Environmental Laws and (ii) relate to actions occurring or conditions

existing on or prior to the Closing Date.  "Hazardous Materials" means any

hazardous or toxic substances, materials or wastes, defined, listed, classified

or regulated as such in or under any Environmental Laws, including, without

limitation, asbestos, petroleum or petroleum products (including gasoline, crude

oil or any fraction thereof), polychlorinated biphenyls, and urea-formaldehyde

stockholders of ALC from a financial point of view, a copy of which opinion has

been delivered to Frontier.

complete copy of each report, schedule, registration statement and definitive

proxy statement filed by Frontier with the SEC since January 1, 1992 (as such

documents have since the time of their filing been amended, the "Frontier SEC

Frontier was required to file with the SEC since such date.  As of their

respective dates, the Frontier SEC Documents complied in all material respects

with the requirements of the Securities Act or the Exchange Act, as the case may

be, and the rules and regulations of the SEC thereunder applicable to such

Frontier SEC Documents, and none of the Frontier SEC Documents contained any

untrue statement of a material fact or omitted to state a material fact required

to be stated therein or necessary to make the statements therein, in light of

the circumstances under which they were made, not misleading.  The financial

statements of Frontier included in the Frontier SEC Documents comply as to form

in all material respects with applicable accounting requirements and with the

published rules and 













<PAGE>
                                                                         30

regulations of the SEC with respect thereto, have been prepared in accordance

with generally accepted accounting principles applied on a consistent basis

during the periods involved (except as may be indicated in the notes thereto or,

in the case of the unaudited statements, as permitted by Form 10-Q of the SEC)

and fairly present the consolidated financial position of Frontier and its

consolidated subsidiaries as at the dates thereof and the consolidated results

of their operations and cash flows for the periods then ended.  All material

agreements, contracts and other documents required to be filed as exhibits to

any of the Frontier SEC Documents have been so filed.

          (e)  Information Supplied.  None of the information supplied or to be

supplied by Frontier or Sub for inclusion or incorporation by reference in (i)

the S-4 will, at the time the S-4 is filed with the SEC and at the time it

material fact or omit to state any material fact required to be stated therein

or necessary to make the statements therein, in light of the circumstances under

which they were made, not misleading and (ii) the Proxy Statement will, at the

date of mailing to stockholders and at the times of the meetings of stockholders

to be held in connection with the Merger, contain any untrue statement of a

material fact or omit to state any material fact required to be stated therein

in all material respects with the provisions of the Exchange Act and the rules

and regulations thereunder, and the S-4, except for such portions thereof that

relate only to ALC, will comply as to form in all material respects with the

provisions of the Securities Act and the rules and regulations thereunder.

          (f)  Compliance with Applicable Laws.  Frontier and its subsidiaries

hold all permits, licenses, variances, exemptions, orders and approvals of all

Governmental Entities which are material to the operation of the businesses of

Frontier and its subsidiaries, taken as a whole (the "Frontier Permits"), except

to the extent the failure to hold the Frontier Permits would not have a material

adverse effect on Frontier.  Frontier and its subsidiaries are in compliance

with the terms of the Frontier Permits and all applicable laws and regulations,

except where the failure so to comply would not have a material adverse effect

on Frontier.  Except as disclosed in the Frontier SEC Documents filed prior to

the date of this Agreement, the businesses of Frontier and its subsidiaries are

not being conducted in violation of any law, order, ordinance or regulation of

any Governmental Entity, except for possible violations which individually or in

the aggregate do not, and, insofar as reasonably can be foreseen, in the future

will not, have a material adverse effect on Frontier.  As of the date of this

Agreement, to the knowledge of Frontier, no investigation by any Government

Entity with respect to Frontier or any of its subsidiaries is pending or

threatened, other than, in each case, those the outcome of which, as far as

reasonably can be foreseen, will not have a material adverse effect on Frontier.

          (g)  Litigation.  As of the date of this Agreement, except as

disclosed in the Frontier SEC Documents filed prior to the date of this

Agreement, there is no suit, action or proceeding pending or, to the knowledge

of Frontier, threatened, against or affecting Frontier or any subsidiary of

Frontier as to which there is a reasonable possibility of an adverse

determination and which, if adversely determined, would, individually or in the

aggregate, have a material adverse effect on Frontier, nor is there any

judgment, decree, injunction, rule or order of any Governmental Entity or

arbitrator outstanding against Frontier or any

                                                                         32

subsidiary of Frontier having, or which, insofar as reasonably can be foreseen,

in the future could have, any such effect.

          (h)  Taxes.  Frontier and each of its subsidiaries (and any

consolidated, combined, unitary or aggregate group for tax purposes of which

Frontier or any of its subsidiaries is or has been a member) have timely filed

all tax returns required to be filed by any of them and have paid (or Frontier

has paid on their behalf), or have set up an adequate reserve for the payment

of, all taxes required to be paid as shown on such returns, and the most recent

financial statements contained in the Frontier SEC Documents reflect an adequate

reserve for all taxes payable by Frontier and its subsidiaries (whether not

shown on such returns) accrued through the date of such financial statements. 

Except as disclosed on Schedule 3.2(h), (i) no material deficiencies for any

taxes have been proposed, asserted or assessed against Frontier or any of its

subsidiaries that are not adequately reserved for, (ii) no audit of any tax

return of Frontier or any of its subsidiaries is being conducted by a tax

authority, and (iii) no extension of the statute of limitations on the

assessment of any taxes has been granted to Frontier or any of its subsidiaries

          (i)  Certain Agreements.  Except as disclosed in the Frontier SEC

Documents filed prior to the date of this Agreement, except as set forth on

Schedule 3.2(i) hereto and except for this Agreement, as of the date of this

Agreement, neither Frontier nor any of its subsidiaries is a party to any oral

or written (i) consulting agreement involving the payment of more than $250,000

per annum, or union, guild or collective bargaining agreement which agreement

covers any employees, (ii) agreement with any executive officer or other key

employee of Frontier or any subsidiary of Frontier the benefits of which are

contingent, or the terms of which are materially altered, upon the occurrence of

a transaction involving Frontier or any subsidiary of Frontier of the nature

contemplated by this Agreement and which













<PAGE>
                                                                         33

provides for the payment of in excess of $250,000, (iii) agreement with respect

to any executive officer of Frontier or any subsidiary of Frontier providing any

term of employment or compensation guarantee extending for a period longer than

one year and for the payment of in excess of $250,000 per annum or (iv)

agreement or plan, including any stock option plan, stock appreciation rights

plan, restricted stock plan or stock purchase plan, any of the benefits of which

will be increased, or the vesting of the benefits of which will be accelerated,

by the occurrence of any of the transactions contemplated by this Agreement or

the value of any of the benefits of which will be calculated on the basis of any

        (ii)  With respect to the Frontier Benefit Plans, individually and in

effect upon Frontier (except liability for benefits claims and funding

applicable law.

       (iii)  True and complete copies of the Frontier Stock Plans as in effect

on the date hereof have been provided to A.

          (k)  Subsidiaries.  Schedule 3.2(k) hereto lists all of the

Significant Subsidiaries of Frontier as of the date hereof, each of which is

wholly-owned by Frontier.  All of the shares of capital stock of each of the

paid and nonassessable and are owned by Frontier or a subsidiary of Frontier

free and clear of any claim, lien or encumbrance.

          (l)  Absence of Certain Changes or Events.  Except as disclosed in the

Frontier SEC Documents filed prior to the date of this Agreement, since December

past practices, nor has there been any change, or any event involving a

prospective change, in the business, prospects, financial condition or results

of operations of Frontier or any of its subsidiaries which has had, or is

reasonably likely to have, a material adverse effect on Frontier (other than as

a result of changes in laws or regulations of general applicability or

interpretations thereof).

          (m)  Section 912 of the NYBCL Not Applicable.  The provisions of

Section 912 of the New York Business Corporation Law (the "NYBCL") will not,

prior to the termination of this Agreement, assuming the accuracy of the

representations contained in Section 3.1(r) (without giving effect to the

knowledge qualification thereof), apply to this Agreement, the Merger or the

transactions contemplated hereby.

          (n)  Vote Required.  The affirmative vote of the holders of shares of

Frontier Common Stock representing a majority of the total votes cast by the

holders of all

                                                                         35

outstanding shares of Frontier Common Stock is the only vote of the holders of

any class or series of Frontier capital stock necessary to approve the Frontier

Frontier Common Stock entitled to vote on the Frontier Vote Matter (assuming for

purposes of this representation (including the proviso) the accuracy of the

representations contained in Section 3.1(r) without giving effect to the

knowledge qualification thereof).

          (o)  Accounting Matters.  Neither Frontier nor, to its best knowledge,

any of its affiliates, has through the date of this Agreement taken or agreed to

take any action that would prevent Frontier from accounting for the business

combination to be effected by the Merger as a "pooling of interests".

          (p)  Frontier Rights Agreement.  Under the Frontier Rights Agreement,

which will be executed as promptly as practicable following the date hereof, and

assuming that no stockholder of ALC would constitute an "Acquiring Person" after

giving effect to the Merger, (i) none of the approval, execution or delivery of

this Agreement or the consummation of the Merger will cause (1) the Frontier

Rights to become exercisable, (2) ALC or any of its subsidiaries to be deemed an

"Acquiring Person" (as defined in the Frontier Rights Agreement), or (3) the

"Stock Acquisition Date" (as defined in the Frontier Rights Agreement) to occur

upon any such event.  The "Distribution Date" (as defined in the Frontier Rights

Agreement) has not occurred.

          (q)  Properties.  Except as disclosed in the Frontier SEC Documents

filed prior to the date of this Agreement or as disclosed in Schedule 3.2(q)

                                                                         36

Frontier or one of its subsidiaries or acquired after the date thereof which are

material to Frontier's business on a consolidated basis (except properties sold

or otherwise disposed of since the date thereof in the ordinary course of

business), free and clear of all claims, liens, charges, security interests or

encumbrances of any nature whatsoever except (A) statutory liens securing

payments not yet due and (B) such imperfections or irregularities of title,

claims, liens, charges, security interests or encumbrances as do not materially

affect the use of the properties or assets subject thereto or affected thereby

or otherwise materially impair business operations at such properties and (ii)

is the lessee of all leasehold estates reflected in the latest audited financial

statements included in such Frontier SEC Documents or acquired after the date

thereof which are material to its business on a consolidated basis (except for

leases that have expired by their terms since the date thereof) and is in

possession of the properties purported to be leased thereunder and each such

lease is valid without default thereunder by the lessee or, to Frontier's

knowledge, the lessor.

          (r)  Ownership of ALC Common Stock.  As of the date hereof, neither

Frontier nor, to its best knowledge, any of its affiliates or associates (as

defined under the Exchange Act), (i) beneficially own, directly or indirectly,

or (ii) are parties to any agreement, arrangement or understanding for the

purpose of acquiring, holding, voting or disposing of, any shares of ALC Common

Stock, except for shares which may be held by Frontier Benefit Plans which

shares do not, in the aggregate, represent 1% or more of the outstanding shares

of ALC Common Stock.

          (s)  Intellectual Property.  Frontier and its Significant Subsidiaries

own or possess adequate licenses or other valid rights to use all material

computer software and firmware, patents, patent rights, trademarks, trademark

rights, trade names, trade name rights, brand names, copyrights, service marks,

trade secrets, applications for trademarks and for

service marks, know-how and other proprietary rights and information used or

held for use in connection with the business of Frontier and its Significant

Subsidiaries as currently conducted or as contemplated to be conducted, and

Frontier is unaware of any assertion or claim challenging the validity of any of

the foregoing which, individually or in the aggregate, would have a material

adverse effect.  To the best knowledge of Frontier, the conduct of the business

of Frontier and its Significant Subsidiaries as currently conducted does not

conflict in any way with any patent, patent right, license, trademark, trademark

right, trade name, trade name right, service mark or copyright of any third

party that, individually or in the aggregate, would have a material adverse

effect.  To the best knowledge of Frontier, there are no infringements of any

proprietary rights owned by or licensed by or to Frontier or any of its

Significant Subsidiaries which, individually or in the aggregate, would have a

material adverse effect.

          (t)  Undisclosed Liabilities.  Except as disclosed in the Frontier SEC

Documents filed prior to the date of this Agreement, neither Frontier nor any of

its Significant Subsidiaries has incurred any liabilities or obligations

(absolute, accrued, contingent or otherwise) other than liabilities or

obligations which would not, individually or in the aggregate, have a material

adverse effect.

          (u)  Environmental Matters.  Except as disclosed in the Frontier SEC

Documents filed prior to the date of this Agreement, there are no Environmental

Liabilities of Frontier or any of its Significant Subsidiaries which would,

individually or in the aggregate, have a material adverse effect.

          (v)  Opinion of Financial Advisor.  Frontier has received the opinion

of Lazard Freres & Co. dated April 9, 1995, to the effect that, as of such date,

the exchange ratio

                                                                         38

reflected in the Conversion Number is fair to the stockholders of Frontier from

a financial point of view, a copy of which opinion has been delivered to ALC.

subsidiaries to, directly or indirectly, through any officer, director, agent or

otherwise, initiate, solicit or knowingly encourage (including by way of

furnishing non-public information or assistance), or take any other action to

facilitate knowingly, any inquiries or the making of any proposal that

negotiate with any person in furtherance of such inquiries or to obtain a

Competing Transaction, or agree to or endorse

with, any person or entity that makes an unsolicited written, bona fide proposal

to acquire such party pursuant to a merger, consolidation, share exchange,

business combination, sale of assets, tender or exchange offer or other similar

transaction, if, and only to the extent that, (A) the Board of Directors of such

party, after consultation with and based upon the advice of independent legal

counsel (who may be such party's regularly engaged independent legal counsel),

determines in good faith that such action is required for the Board of Directors

of such party to comply with its fiduciary duties to stockholders under

applicable law and (B) prior to furnishing such information to, or entering into

discussions or negotiations with, such person, such party (x) provides

reasonable notice (no less than one business day) to the other party to the

effect that it is furnishing information to, or entering into discussions or

negotiations with, such person and (y) receives from such person an executed

such person or entity any material, non-public information not previously

delivered to the other party shall deliver to the other party copies of all such

information (provided that the party furnishing to any such person any such

legal counsel (who may be such party's regularly engaged independent legal

counsel), determines in good faith that such action is required for the Board of

Directors of such party to comply with its fiduciary duties to stockholders

Subsidiaries:  (i) any merger, consolidation, share exchange, business

Section 4.1(e) shall not prohibit accurate disclosure by a party that is

required in any ALC SEC Document or Frontier SEC Document (including the Proxy

Statement and the S-4) or otherwise under applicable law in the opinion of the

Board of Directors of such party, after consultation with and based upon the

advice of independent legal counsel (who may be such party's regularly engaged

partnership, association or other business organization or division thereof or

otherwise acquire or agree to acquire any assets in each case which are

material, individually or in the aggregate, to such party and its subsidiaries

taken as a whole; provided, however, that the foregoing shall not prohibit (i)

internal reorganizations or consolidations involving existing subsidiaries or

(ii) the creation of new subsidiaries organized to conduct or continue

activities otherwise permitted by this Agreement.

                                                                         44

          (g)  No Dispositions.  Other than (i) dispositions referred to in ALC

SEC Documents or Frontier SEC Documents filed prior to the date of this

Agreement or as previously disclosed in writing by a party to the other party,

or (ii) as may be required by law to consummate the transactions contemplated

hereby, no party shall, or shall permit any of its subsidiaries to, sell, lease,

or which, in the aggregate, do not exceed $25,000,000.

          (h)  Indebtedness.  No party shall, or shall permit any of its

subsidiaries to, incur any long-term indebtedness for borrowed money or

guarantee any such long-term indebtedness or issue or sell any long-term debt

enter into or amend any contract, agreement, commitment or arrangement with

respect to any of the foregoing, other than (i) in replacement for existing or

          (i)  Other Actions.  No party shall, or shall permit any of its

subsidiaries to, take any action that would or reasonably might be expected to,

result in any of its representations and warranties set forth in this Agreement

being or becoming untrue in any material respect, or in any of the conditions to

the Merger set forth in Article VI not being satisfied, or (unless such action

is required by applicable law) which would adversely affect the ability of any

of them to obtain any of the Requisite Regulatory Approvals without imposition

of a condition or restriction of the type referred to in Sections 6.1(g), 6.2(e)

or 6.3(e).

          (j)  Advice of Changes; Government Filings.  Each party shall confer

on a regular and frequent basis with the other, report on operational matters

and promptly advise the other, orally and in writing of any change or event

having, or which, insofar as can reasonably be foreseen, could have, a material

adverse effect on such party or which would cause or constitute a material

breach of any of the representations, warrants or covenants of such party

contained herein.  Frontier and ALC shall file all reports required to be filed

by each of them with the SEC between the date of this Agreement and the

Effective Time and shall deliver to the other party copies of all such reports

promptly after the same are filed.  Frontier and ALC shall cooperate with each

other in determining whether any filings are required to be made with or

consents required to be obtained from, any third party or Governmental Entity

prior to the Effective Time in connection with this Agreement or the

transactions contemplated hereby, and shall cooperate in making any such filings

promptly and in seeking to obtain timely any such consents.  Each party shall

promptly provide the other (or its counsel) with copies of all other filings

made by such party with any state or federal Governmental Entity in connection

with this Agreement or the transactions contemplated hereby.

          (k)  Accounting Methods.  Neither Frontier nor ALC shall change its

methods of accounting in effect at December 31, 1994, except as required by

changes in generally accepted accounting principles as concurred in by such

party's independent auditors.  Neither Frontier nor ALC will change its fiscal

year.

          (l)  Pooling and Tax-Free Reorganization Treatment.  Neither Frontier

nor ALC shall intentionally take or cause to be taken any action, whether before

or after the Effective Time, which would disqualify the Merger as a "pooling of

interests" for accounting purposes or as a "reorganization" within the meaning

of Section 368(a) of the Code.

          (m)  Benefit Plans.  During the period from the date of this Agreement

and continuing until the Effective Time, each of Frontier and ALC agrees as to

itself and its subsidiaries that it will not, without the prior written consent

of the other party, (i) enter into, adopt, amend (except as may be required by

law), renew or terminate any Frontier Benefit Plan or ALC Benefit Plan, as the

case may be, or any other employee benefit plan or any agreement, arrangement,

plan or policy between such party and one or more of its directors or officers,

(ii) except for normal increases in the ordinary course of business consistent

with past practice that, in the aggregate, do not result in a material increase

in benefits or compensation expense to such party, increase in any manner the

compensation or fringe benefits of any director, officer or employee or pay any

benefit not required by any plan and arrangement as in effect as of the date

hereof, (iii) in the case of ALC, grant any stock options, stock appreciation

rights, restricted stock, restricted stock units or performance units or shares

other than as required by existing agreements with individual employees, or

enter into any contract, agreement, commitment or arrangement to do any of the

foregoing or (iv) except for the Employment Agreements, enter into or renew any

contract, agreement, commitment or arrangement providing for the payment to any

director, officer or employee of

such party of compensation or benefits contingent, or the terms of which are

materially altered, upon the occurrence of any of the transactions contemplated

by this Agreement. 

          (n)  Tax Elections.  Except in the ordinary course of business and

consistent with past practice, without the prior written consent of the other,

neither Frontier nor ALC shall make any material tax election or settle or

compromise any material federal, state, local or foreign income tax liability.

          (o)  Network Transition.  Promptly following the date hereof, Frontier

and ALC shall consider and discuss the manner in which they may, to the extent

not violative of any contracts, arrangements or agreements, written or oral, to

which any party hereto or any of its subsidiaries or affiliates is a party,

cause their respective long distance subsidiaries (the "Long Distance Subs") to

take the actions reasonably necessary to begin to transition their respective

switched long distance traffic of each other for termination and obtain the

maximum network optimization and other synergies as necessary for the Long

efforts to have the S-4 declared effective under the Securities Act as promptly

as practicable after such filing.  Frontier shall also take any action (other

than qualifying to do business in any jurisdiction in which it is now not so

qualified) required to be taken under any applicable state securities laws in

connection with

                                                                         48

upon the exercise of the ALC Stock Options and the ALC Warrants, and ALC shall

furnish all information concerning ALC and the holders of ALC Common Stock, ALC

Stock Options and ALC Warrants as may be reasonably requested in connection with

any such action.

          5.2  Letter of ALC's Accountants.  ALC shall use its reasonable best

efforts to cause to be delivered to Frontier a letter of Ernst & Young, ALC's

independent auditors, dated a date within two business days before the date on

which the S-4 shall become effective and addressed to Frontier, in form and

substance reasonably satisfactory to Frontier and customary in scope and

substance for letters delivered by independent public accountants in connection

with registration statements similar to the S-4.

          5.3  Letter of Frontier's Accountants.  Frontier shall use its

reasonable best efforts to cause to be delivered to ALC a letter of Price

Waterhouse, Frontier's independent auditors, dated a date within two business

days before the date on which the S-4 shall become effective and addressed to

ALC, in form and substance reasonably satisfactory to ALC and customary in scope

and substance for letters delivered by independent public accountants in

connection with registration statements similar to the S-4.

          5.4  Access to Information.  Upon reasonable notice, ALC and Frontier

shall each (and shall cause each of their respective subsidiaries to) afford to

the officers, employees, accountants, counsel and other representatives of the

other, access, during normal business hours during the period prior to the

Effective Time, to all its properties, books, contracts, commitments and records

and, during such period, each of ALC and Frontier shall (and shall cause each of

their respective subsidiaries to) make available to the other (a) a copy of each

it during such period pursuant to the requirements of federal securities laws

                                                                         49

information concerning its business, properties and personnel as such other

party may reasonably request.  The parties will hold any such information which

is nonpublic in confidence to the extent required by, and in accordance with,

the provisions of the Confidentiality Agreement.  No investigation by either

Frontier or ALC shall affect the representations and warranties of the other,

except to the extent such representations and warranties are by their terms

qualified by disclosures made to such first party.

          5.5  Stockholder Meetings.  ALC and Frontier each shall call a meeting

of its respective stockholders to be held as promptly as practicable for the

purpose of voting upon the approval of this Agreement in the case of ALC and the

Frontier Vote Matter in the case of Frontier.  ALC and Frontier will, through

their respective Boards of Directors, recommend to their respective stockholders

approval of such matters, unless otherwise required under the applicable

fiduciary duties of the respective directors of ALC and Frontier, as determined

by such directors in good faith after consultation with and based upon the

advice of independent legal counsel (who may be such party's regularly engaged

independent legal counsel).  ALC and Frontier shall coordinate and cooperate

with respect to the timing of such meetings and shall use their best efforts to

hold such meetings on the same day and as soon as practicable after the date on

which the S-4 becomes effective.  This Section 5.5 shall not prohibit accurate

disclosure by a party that is required in any ALC SEC Document or Frontier SEC

Document (including the Proxy Statement and the S-4) or otherwise under

applicable law of the opinion of the Board of Directors of such party as of the

date of such SEC Document or such other required disclosure as to the

transactions contemplated hereby or as to any takeover proposal.

          5.6  Legal Conditions to Merger.  Each of ALC and Frontier shall, and

shall cause its subsidiaries to, use all reasonable efforts (i) to take, or

cause to be taken, all actions 















<PAGE>
                                                                         50

necessary to comply promptly with all legal requirements which may be imposed on

such party or its subsidiaries with respect to the Merger and to consummate the

transactions contemplated by this Agreement, subject to the appropriate vote of

stockholders of ALC and Frontier described in Section 6.1(a), and (ii) to obtain

(and to cooperate with the other party to obtain) any consent, authorization,

order or approval of, or any exemption by, any Governmental Entity and or any

other public or private third party which is required to be obtained or made by

such party or any of its subsidiaries in connection with the Merger and the

transactions contemplated by this Agreement; provided, however, that a party

shall not be obligated to take any action pursuant to the foregoing if the

taking of such action or such compliance or the obtaining of such consent,

authorization, order, approval or exemption is likely, in such party's

reasonable opinion, (x) to be materially burdensome to such party and its

subsidiaries taken as a whole or to impact in a materially adverse manner the

economic or business benefits of the transactions contemplated by this Agreement

so as to render inadvisable the consummation of the Merger or (y) to result in

the imposition of a condition or restriction on such party or on the Surviving

Corporation of the type referred to in Sections 6.1(g), 6.2(e) or 6.3(e).  Each

of ALC and Frontier will promptly cooperate with and furnish information to the

other in connection with any such burden suffered by, or requirement imposed

upon, any of them or any of their subsidiaries in connection with the foregoing.

          5.7  Affiliates.  At least 40 days prior to the Closing Date, ALC

shall deliver to Frontier a letter identifying all persons who are, at the time

this Agreement is submitted for approval to the stockholders of ALC,

"affiliates" of ALC for purposes of Rule 145 under the Securities Act.  ALC

shall use all reasonable efforts to cause each person named on the letter

delivered by it to deliver to Frontier at least 30 days prior to the Closing

Date a written agreement, substantially in the form attached as Exhibit 5.7.

                                                                         51

          5.8  Stock Exchange Listing.  Frontier shall use all reasonable

efforts to cause the shares of Frontier Common Stock to be issued in the Merger

and the shares of Frontier Common Stock to be reserved for issuance upon

exercise of ALC Stock Options and ALC Warrants to be approved for listing on the

NYSE, subject to official notice of issuance, prior to the Closing Date.

          5.9  Employee Benefit Plans.  Following the Effective Time, Frontier

shall establish, or maintain, in good faith, Benefit Plans for the Surviving

Corporation and its subsidiaries effective as of the Effective Time.  Except as

otherwise provided in Section 5.10, in the case of ALC Benefit Plans under which

the employees' interests are based upon ALC Common Stock, Frontier and ALC agree

that such interests shall be based on Frontier Common Stock in an equitable

manner.

          5.10  Stock Options and Warrants.  (a)  At the Effective Time, each

outstanding ALC Stock Option and ALC SAR, in each case whether vested or

unvested, and ALC Warrant shall be assumed by Frontier.  Each ALC Stock Option

shall be deemed to constitute an option to acquire, and each ALC Warrant shall

be deemed to constitute a warrant to acquire, on the same terms and conditions

as were applicable under such ALC Stock Option or such ALC Warrant, as the case

may be, the same number of shares of Frontier Common Stock as the holder of such

ALC Stock Option or such ALC Warrant, as the case may be, would have been

entitled to receive pursuant to the Merger had such holder exercised such ALC

Stock Option or ALC Warrant in full immediately prior to the Effective Time, at

a price per share equal to (y) the aggregate exercise price for the shares of

ALC Common Stock otherwise purchasable pursuant to such ALC Stock Option or ALC

Warrant divided by (z) the number of full shares of Frontier Common Stock deemed

purchasable pursuant to such ALC Stock Option or ALC Warrant; provided, however,

that in the case of

















<PAGE>
                                                                         52

any option to which section 421 of the Code applies by reason of its

qualification under section 422 of the Code ("qualified stock options"), the

option price, the number of shares purchasable pursuant to such option and the

terms and conditions of exercise of such option shall be determined in order to

comply with section 424(a) of the Code.  Each holder of an ALC SAR shall be

entitled to that number of stock appreciation rights of Frontier determined in

the same manner as set forth above with respect to ALC Stock Options assumed by

Frontier.  As soon as practicable following the date of this Agreement, the

Board of Directors of ALC (and/or the appropriate committee thereof) shall take

all other actions necessary in order to effectuate the foregoing and to ensure

that following the Effective Time no holder of an ALC Stock Option, ALC SAR or

ALC Warrant nor any participant in any ALC Benefit Plan shall have any right

thereunder to acquire equity securities of ALC or the Surviving Corporation.

          (b)  ALC shall deliver to the holders of the Warrants appropriate

notices setting forth such holders' rights in connection with the Merger in

accordance with the provisions of the respective Warrant Agreements.  As soon as

practicable after the Effective Time, Frontier shall deliver to the holders of

ALC Stock Options and ALC SARs appropriate notices setting forth such holders'

rights pursuant to the ALC Stock Plans in connection with the Merger.  The

agreements evidencing the grants of ALC Stock Options, ALC SARs or ALC Warrants,

as the case may be, shall continue in effect on the same terms and conditions

(subject to the adjustments required by this Section 5.10 after giving effect to

the Merger and the assumption by Frontier as set forth above).  If necessary,

Frontier shall use its reasonable best efforts to comply with the terms of the

ALC Stock Plans and to ensure, to the extent required by, and subject to the

provisions of, the ALC Stock Plans, that ALC Stock Options

                                                                         53

which qualified as qualified stock options prior to the Effective Time continue

to qualify as qualified stock options of Frontier after the Effective Time.

          (c)  Frontier shall take all corporate action necessary to reserve for

issuance a sufficient number of shares of Frontier Common Stock for delivery

upon exercise of ALC Stock Options and ALC Warrants assumed by it in accordance

with this Section 5.10.  As soon as practicable after the Effective Time,

Frontier shall file one or more registration statements on appropriate forms

with respect to the shares of Frontier Common Stock subject to such ALC Stock

Options and, to the extent required by the respective Warrant Agreements, with

respect to the shares of Frontier Common Stock subject to such ALC Warrants, and

shall use its best efforts to maintain the effectiveness of such registration

statement or registration statements for so long as such options or warrants, as

applicable, remain outstanding.

          5.11  Brokers or Finders.  Except as disclosed to the other party

prior to the date hereof, each of Frontier and ALC represents, as to itself, its

subsidiaries and its affiliates, that no agent, broker, investment banker,

financial advisor or other firm or person is or will be entitled to any broker's

or finder's fee or any other commission or similar fee in connection with any of

the transactions contemplated by this Agreement, except Salomon Brothers Inc,

whose fees and expenses will be paid by ALC in accordance with ALC's agreement

with such firm (a copy of which has been delivered by ALC to Frontier prior to

the date of this Agreement), and Lazard Freres & Co., whose fees and expenses

will be paid by Frontier in accordance with Frontier's agreement with such firm

(a copy of which has been delivered by Frontier to ALC prior to the date of this

Agreement), and each party agrees to indemnify the other party and hold the

other party harmless from and against any and all claims, liabilities or

obligations with respect to any other fees, commissions or expenses

                                                                         54

asserted by any person on the basis of any act or statement alleged to have been

made by such first party or its affiliate.

          5.12  Governance.  (a)  Frontier's Board of Directors shall take

action to cause John M. Zrno, William H. Oberlin, Richard J. Uhl and Michael E.

Faherty to be elected to Frontier's Board of Directors as of the Effective Time

or as soon thereafter as practical.  Frontier's Board of Directors shall amend

Frontier's By-laws to increase the size of the Frontier Board of Directors to

the extent necessary to comply with this Section.  Frontier's Board of Directors

shall also take action to cause the persons set forth on Exhibit 5.12 to be

elected to the offices specified in such Exhibit effective as of the Effective

Time. 

          (b)  ALC shall use its reasonable best efforts to obtain the

resignation of each director of ALC effective as of the Effective Time.

          5.13  Indemnification; Directors' and Officers' Insurance.  (a)  From

and after the Effective Time, Frontier shall, or shall cause the Surviving

Corporation to, indemnify, defend and hold harmless each person who is now, or

has been at any time prior to the date hereof or who becomes prior to the

Effective Time, an officer, director or employee of ALC or any of its

subsidiaries (the "Indemnified Parties") against (i) all losses, claims,

damages, costs, expenses, liabilities or judgments or amounts that are paid in

settlement with the approval of Frontier (which approval shall not be

unreasonably withheld) of or in connection with any claim, action, suit,

proceeding or investigation based in whole or in part on or arising in whole or

in part out of the fact that such person is or was a director, officer or

employee of ALC or any subsidiary of ALC, whether pertaining to any matter

existing or occurring at or prior to the Effective Time and whether asserted or

claimed prior to, or at or after, the Effective Time ("Indemnified Liabilities")

and (ii) all Indemnified Liabilities based in whole or in part on, or arising in

whole or in part out of, or pertaining to this Agreement













<PAGE>
                                                                         55

or the transactions contemplated hereby, in each case to the full extent ALC

would have been permitted under Delaware law and its Certificate of

Incorporation and By-laws to indemnify such person, consistent with applicable

law (and Frontier shall pay expenses (including attorneys' fees)  in advance of

the final disposition of any such action or proceeding to each Indemnified Party

to the full extent permitted by law upon receipt of any undertaking required by

applicable law).  Without limiting the foregoing, in the event any such claim,

action, suit, proceeding or investigation is brought against any Indemnified

Party (whether arising before or after the Effective Time), (i) any counsel

retained by the Indemnified Parties for any period after the Effective Time

shall be reasonably satisfactory to Frontier and (ii) after the Effective Time,

Frontier will use all reasonable efforts to assist in the vigorous defense of

any such matter, provided that Frontier shall not be liable for any settlement

of any claim effected without its written consent, which consent, however, shall

not be unreasonably withheld.  Any Indemnified Party wishing to claim

indemnification under this Section 5.13, upon learning of any such claim,

action, suit, proceeding or investigation, shall notify Frontier (but the

failure so to notify Frontier shall not relieve it from any liability which it

may have under this Section 5.13 except to the extent such failure materially

prejudices Frontier), and shall deliver to Frontier any undertaking required by

applicable law.  The Indemnified Parties as a group may retain only one law firm

to represent them with respect to each such matter unless there is, under

applicable standards of professional conduct, a conflict on any significant

issue between the positions of any two or more Indemnified Parties.

          (b)  For a period of seven years after the Effective Time, Frontier

shall cause to be maintained in effect the current policies of directors' and

officers' liability insurance maintained by ALC (provided that Frontier may

substitute therefor policies of at least the same coverage and amounts

containing terms and conditions which are no less 













<PAGE>
                                                                         56

advantageous) with respect to claims arising from facts or events which occurred

before the Effective Time; provided, however, that Frontier shall not be

obligated to make annual premium payments for such insurance to the extent such

premiums exceed 200% of the premiums paid as of the date hereof by ALC for such

insurance.  Notwithstanding anything to the contrary contained elsewhere herein,

Frontier's agreement set forth above shall be limited to cover claims only to

the extent that those claims are not covered under ALC's directors' and

officers' insurance policies (or any substitute policies permitted by this

Section 5.13(b)).

          (c)  The provisions of this Section 5.13 are intended to be for the

benefit of, and shall be enforceable by, each Indemnified Party, and his or her

heirs and representatives.

          5.14  Elimination of Certain Restrictions.  The parties shall make all

reasonable efforts to eliminate the application, after the Effective Time, of

certain restrictive covenants contained in the Indenture dated as of May 15,

1993 among Allnet Communication Services, Inc., ALC and Star Bank, National

Association, as Trustee, relating to ALC's 9% Senior Subordinated Notes due May

15, 2003, by such means, including without limitation, consent, amendment or

defeasance, as may be mutually agreeable.

          5.15  Financial Reporting.  If the Effective Time shall have occurred

in either the first or last month of a fiscal quarter of Frontier, Frontier

shall seek to accelerate the release of 30 days of combined earnings of Frontier

and the Surviving Corporation to the fullest extent reasonably practicable,

taking into account the best interests of Frontier.

          5.16  Additional Agreements.  In case at any time after the Effective

Time any further action is necessary or desirable to carry out the purposes of

this Agreement or to vest the Surviving Corporation with full title to all

properties, assets, rights, approvals, immunities and franchises of either Sub

or ALC, the proper officers and directors of each party to this Agreement shall

take all such necessary action.

ALC stockholders pursuant to this Agreement and such other shares required to be

pending.  There shall not be any action taken, or any statute, rule, regulation

or order enacted, entered, enforced or deemed applicable to the Merger, which

makes the consummation of the Merger illegal.

          (f)  Pooling.  Frontier and ALC shall have received letters from Price

Waterhouse and from Ernst & Young to the effect that the Merger qualifies for

"pooling of interests" accounting treatment if consummated in accordance with

this Agreement.

          (g)  Burdensome Condition.  There shall not be any action taken, or

any statute, rule, regulation or order enacted, entered, enforced or deemed

applicable to the Merger, by any federal or state Governmental Entity which, in

connection with the grant of a Requisite Regulatory Approval, imposes any

condition or restriction upon Frontier or its subsidiaries (after giving effect

to the Merger) which would so materially adversely impact the economic or

business benefits of the transactions contemplated by this Agreement as to

render inadvisable the consummation of the Merger, provided that the parties
                                                   --------

instrument, except those for which failure to obtain such consents and

approvals, or to make such filings or deliveries, would not, in the reasonable

reorganization within the meaning of Section 368(b) of the Code, which opinion

shall not have been withdrawn or modified in any material respect.

any requirement upon ALC or its subsidiaries to dispose of any asset which would

be deemed to constitute a significant amount of assets to Frontier (after giving

effect to the Merger) under Instruction 4 of Item 2 of Form 8-K, provided that
                                                                 --------

FOR IMMEDIATE RELEASE


        Frontier Corporation and ALC Communications Corporation Announce


                         Definitive Agreement to Merge


                  $1.8 Billion Deal Creates Fifth Largest

                        Long Distance Company in U.S.



New York, NY, April 10, 1995 -- Frontier Corporation (NYSE:FRO) and ALC 

Communications Corporation (AMEX: ALC) today announced the two companies have 

signed a definitive agreement to merge, creating the fifth-largest long distance

company in the U.S. This transaction firmly establishes the combined company,

which will operate under the name Frontier Corporation, as a nationwide leader

in this rapidly consolidating high-growth industry. This synergistic merger of

equals will create a combined company with consolidated revenues approaching

$2 billion, and long distance revenues in the $1.4 billion range -- ranking the

new company behind only AT&T, MCI, Sprint and LDDS. The Boards of Directors of

both companies have approved the merger.



Under the terms of the merger agreement, shareowners of ALC will receive a

total of 79.3 million shares (equivalent to 49% of the combined company's

shares) of Frontier common stock, or 2.0 shares of Frontier for each share

of ALC stock. Based on the approximately 39.7 million 

<PAGE>

                                                                           2

shares of ALC stock outstanding and the closing stock price of Frontier on

Friday, April 7,1995, the transaction will have a total value of approximately

$1.8 billion. The merger is intended to qualify as a tax-free reorganization

and a "pooling of interests" for accounting and financial purposes.



"With this merger, Frontier is superbly positioned as an emerging force in the

high-growth long distance telephone industry," said Ronald L. Bittner, Chairman

and Chief Executive Officer of Frontier. "By combining the rapidly expanding

long distance businesses at Frontier and ALC, we have achieved critical size

and scope -- two strategic elements necessary for long-term success in this

industry. On its own, each company has a demonstrated track record of superior

revenue and customer growth in the long distance industry and now together, we

expect to be at the forefront of the changing telecommunications landscape."



"This combination is a perfect fit of operating philosophies, cultures,

products, and services," said John M. Zrno, President and Chief Executive

Officer of ALC. "ALC, like Frontier, has successfully focused its strategy on

bundling a portfolio of high-quality, integrated communications services to

its customers. By creating an even more powerful long distance franchise, we

expect additional opportunities to provide these bundled services."



The merger of Frontier and ALC brings together two success stories and 

immediately creates one of the most innovative telecommunications companies 

in the U.S. Frontier's $500 million long 


<PAGE>

                                                             3

distance business, its strong financial condition, superior cash flow and

loyal customer base are a natural fit with ALC's established position as one of

the best managed and fastest growing companies in the long distance industry.

The combined company will serve nearly two million customers throughout the U.S.



Executives from both Frontier and ALC will assume critical management roles

at the new company, creating one of the strongest and most progressive 

management teams in the industry. The structure of the new management team is:

Ronald L. Bittner, Chairman of the Board and Chief Executive Officer; John M.

Zrno, Vice Chairman of the Board; William H. Oberlin, President and Chief

Operating Officer; Marvin C. Moses, Chief Financial Officer; Louis L. Massaro, 

Chief Administrative and Technology Officer; Dale M. Gregory, President, Long

Distance; Jeremiah T. Carr, President, Telephone; and James Whelehan, President,

Wireless.  Messrs. Zrno and Oberlin, as well as two of ALC's current outside 

Directors will join the enlarged Frontier Board. The company will appoint a 

transition team consisting of senior officers which will oversee organizational

issues and assure the integration of the combined long distance customer base.



The ALC senior management team has signed long-term employment contracts with

Frontier, effective upon completion of the transaction.

Both companies expect to report first quarter results within 10 days. ALC 

expects to report results that are somewhat ahead of current analyst

expectations, while Frontier expects its results to be in line with current 

Wall Street earnings expectations. Based On current Wall Street estimates and 

targeted synergies of at least $40 million annually, the company would 

experience greater than 10% earnings dilution in 1995 as a result of this

transaction, diminishing significantly in 1996 to less than 5% and becoming 

accretive to earnings in 1997. "Our plan is to reduce costs through significant

network efficiencies, lowering corporate expenses and overhead, and combining 

operations. At the same time we will be increasing revenues by reducing customer

attrition and cross-selling each others' products to a larger customer base,"

said Mr. Bittner.



The combined company will have total consolidated long distance, local and 

cellular revenues approaching $2 billion and more than 6,500 employees 

throughout the U.S. Long distance revenues are expected to account for 

approximately 70% of the total.



This merger represents fulfillment of the two companies objectives and allows 

the combined company to expand aggressively into the domestic and international

long distance business. In addition to this merger, Frontier recently completed

the acquisition of American Sharecom and is expected to close on the announced

WCT Communications acquisition in May 1995. ALC has also recently completed the

acquisition of ConferTech International, Inc.

At the Frontier Board of Directors meeting which approved the merger agreement,

the Directors also adopted a Shareowner Rights Plan, which protects existing 

shareowners from unsolicited and unreasonable takeover offers. ALC's Board of 

Directors approved a similar rights plan several months ago.



The merger is subject to the approval of shareowners of Frontier and ALC at 

separate meetings anticipated in August, 1995 and other customary conditions.



Frontier recently increased its dividend in December, 1994 and the company 

anticipates no change in its dividend policy as a result of this merger.



Advisors on the transactions were Lazard Freres & Co. for Frontier Corporation

and Salomon Brothers for ALC Corporation.



Frontier is a provider of integrated telecommunications solutions to more than

1.5 million customers through its long distance, local telephone and wireless

communications operations. Incorporated in 1920 as Rochester Telephone 

Corporation and named Frontier on January 1, 1995, the company's landmark Open

Market Plan makes it the first in the nation to open a local telephone market 

to competition.

ALC, through its wholly-owned subsidiary Allnet Communications Services, 

Inc. provides long distance products and services to small to medium-sized 

business customers nationwide. Recently, Allnet announced the offering of 

cellular and paging services to customers nationwide and continues to focus on

expanding communications services both domestically and internationally.
